Make link between 2 functions of a controller
Rate Topic:

I would like to pass a value from a function to another in the same controller.
My problem is :

I set 'arg' in the A function.
But at the end of the function A, I render the A view.
So when I call the function B, from the view of the A view, it founds a 'arg' empty...
Like if the controller was built at each call to a function, and destroy when the view is render.

So I don't know how to pass the value of 'arg' from A to B...
I don't know where to save the value 'arg' to call it later.

I would like to let it in the same object, I'm feeling this cleaner to do it like that...

When you display a view... a server/client request/response is finished, so any call from that view is a new request/response and at that time the controller/model is again created and you have to assign again the values you need...

That was what I thinking...thx
I've tried to pass the parameter by POST but it definitely tell me the same thing each time : undifined index 'arg'
I obviously test my parameter in my B function with isset, but it seems to don't want to work...
In fact everything is fine until I render the view where a don't recognize the parameter anymore, in the controller everything is fine...
